Editor’s note: The following review is part of Macworld’s GemFest 2012 series. Every weekday from mid June through mid August, the Macworld staff will use the Mac Gems blog to briefly cover a favorite free or low-cost program. Visit the Mac Gems homepage for a list of past Mac Gems.
We’ve covered a good number of Gems that can display your laptop’s battery status in the menu bar. But Battery Status (Mac App Store link) offers a unique twist that will appeal to Mac laptop and desktop users who also own Apple’s Magic Trackpad, Magic Mouse, or Wireless Keyboard. It offers information about the battery status of each of those devices, as well.
Clicking Battery Status’s menu-bar icon, and the resulting menu displays information about all your batteries. For Apple’s Bluetooth peripherals, you see the percentage charge remaining, as well as an estimate of when the battery will run out of juice. If you’ve replaced a battery since you started using Battery Status, you’ll also see the date of that change.
You can get the percentage of battery life remaining for the Magic Trackpad, Magic Mouse, and Wireless Keyboard via a submenu in Apple’s Bluetooth menu, but it’s a hassle to get to, and Battery Status offers more information. The fact that Battery Status lets you use a single menu-bar space to monitor all your batteries makes it both useful and prudent.
